HINGE STRUCTURE FOR SIDEWALK DOORS Application led December 15, 1928.

This invention relates to what are known as bulkhead or sidewalk doors and particularly to means for hingedly supporting these doors. The customary mannerV of hinging sidewalk doors is to use a hinge consisting of two butts with a bronze pin connecting them. These doors usually have4 a steel channel frame constituting the door frame itself and usually embedded in concrete and it has been proposed to drill oppositely disposed holes in the channel frame and use steel pins or dowels on the door allowing the pins to pass through the holes, the pins thus constituting pivot pins upon which the doors can swing. This method of hinging doors is economical but unsatisfactory owing to the fact that it is difficult to insert the door, the door must be put in place and hinged before the door frame is made up and the holes through the channel for the pivot pins become clogged with dirt both from the inside and outside. Furthermore, the constant using of the door enlarges the holes, making the hinge loose.

Vith this in mind, the general object of my invention is to provide a means for hinging the sidewalk door to the frame thereof which will permit the door -to be disposed within the frame and Vmounted thereon after the frame is set in place and which will permit the door to be set very expeditiously and at a minimum of time and expense.

A further object is to provide a construction of such character that the door may be readily removed with its supporting members at any time and as readily replaced, thus permitting the supporting members to be replaced by new ones if the old supporting members are worn at the pintle or permitting the replacement of the pintle if the pintle is worn.

A further'object is to provide a construction of this character which will permitthe door to fit snugly in place within the door frame and to provide means whereby the water leaking through the door will be taken careof and discharged.

Other objects will appear in the course of the following description.

,the under face of the door.

'serial No. 326,259.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a fragmentary top plan View of a sidewalk door having my improved hinge structure applied thereto;

Figure 2 is an elevation partly in section, the section being taken on the line 2 2 of Figure l;

Figure 3 is a section on the line S-Sof Figure 2, but showing the door closed;

Figure if is an elevation of a modification of the supporting plate for the door.

Referring to these drawings, 10 designates a portion of the rectangular frame of the door. This frame as shown in Figure 2 is illustrated as made of channel iron though, of course, l do not wish to be limited to the use of channel iron for this purpose. Forming part of the door frame and attached to the lower flange of the channel iron l() is the lower flange 11 of an angle iron whose flange 12 extends upward in spaced relation to the web of the channel iron 10 so as to form a gutter 13. This gutter 13' extends entirely around the frame on the inside thereof and at one point is providedwith a drainage opening connected by pipe to the sewer in an obvious manner so as to permit any drainage seeping in around the door to 'be vcarried away.

The door 14: is preferably lmade of steel,

or any other suitable material, braced by angle irons or channel irons and as illustrated carries bolted, riveted or otherwise attached to its under face at the butt endends of a transverse bar 15 but may be made independently of each other and attached to The door has a width approximately equal' to the interior widthA of the frame 10 so as to fit down between said frame. For the purpose of supporting the door, I provide the door supportingorrhinge members 17 which may be made of any suitable material but are preferably made of bronze castings. There are two of these hinge members which are i disposed at the corners of the frame so as Yhorizontal position.

17v is apertured at21 forvthe reception of to abut at their rear ends against the rear of the frame and lit closely against the inner faces of the frame.

The top edge of each of these hinge menibers is flush with the upper edge of the frame beam 10 but each hinge member is cut away at 18 to a depth equal to the thickness of the door so that the door er leaf when turned down may rest upon the upperface of this cut away portion. Inorder to accommodate the portion 19 which is rearward of the recess 18, the lateral edges of the 'door' at its rear corners are Acut away at 20 so that the door may swing from a vertical to a Each of the members the corresponding gudgeon 16 and also apertured for the passage of a plurality of bolts or screws 22. These bolts or screws extend through the member 17 and through the web of the frame beam 10. Preferably the web or frame beam will be tapped so that the bolts will have screw-threaded engagement therewith though it will be understood that nuts might ybe used in connection with these bolts. Y i,

It will, of course, be noted that neither gudgeon 16 extends into the web of the channel iron'frame beam. In the construction shown in Figure 3, each hinge member 17 is formed at its rear end with a downwardly extending leg 23 which bears against the bottom of the gutter 13 at the rear end of this gutter. I do not wish to be limited to this, however, as the member 17 might be formed without this leg as shown in Figure 4.

Metallic strips or blocks 24 are bolted, riveted or otherwise attached to the web of the opposedaiigle iron frames, and these blocks or strips extend along the fraine oii a level with the upper edge faces of the hinge members 17 so as to support the door when the door is in a horizontal position.

It will be understood that ordinarily there are two of these doors mounted within one single frame. ris before remarked, I do not wish to be limited to the use of a pintle baii 15 extending entirely across the door as while this is the best practice as reinforcing the door at this point and `giving full support, it would be entirely possible to form the gudgeons as separate elements attached to the door. i

It will be seen that the hinge mounting of this door is such that the doormay be readily put in place and as readily removed ataiiyrv time and that when the door is closed, the hinge mounting is entirely protected so that the door cannot be detached by releasing the hinge. Furthermore, it will be seen that this hinge mounting permits the door to be put in place after the frame of the door has been set in concrete or other material and that with this construction, there is no chance of the apertures for the gudgeons becoming more or less filled with concrete in the operation of setting the door frame and that there is no likelihood of the apertures or seats for the gudgeons becoming filled with dust or dirt, thus making the door hard to open and close. Y v

The door is held snugly iii place against any lateral movement for the reason that thevpintles atftheir ends abut against the web of the channel iron frame. The door when closed'iits closely against the channel iron framevat its edges and any water which may seep in around the edges of the door ,Y will be caught in the gutter 13 and drained acter stated and does away with the trouble" so often found in sidewalk doors ofthe hinge butts becoming loese. Y

My construction while providing relatively heavy gudgeons uponA which the door operates entirely overcomes the ditliculties" heretofore experienced in the use of these gudgeons and the trouble in setting the door incident thereto. v,

It will also be noted that inasmuch as the hinge elements, blocks or plates 17 abut'fgg,

against the side and end channel irons of theV frame and are disposed in engagement with the corners of the frame, that they are very easily set in place without measurements,

without careful calculation and by unskilled.r

labor, and all thatit is necessary to do is to be sure that the bolt holes for these hinge elements are so disposed that the upper edge of the hinge element is exactly flush with the upper face of the channel iron frame?? The downwardly extending leg 23 has the added advantage that it forms a guide kwhereby the hinge member may be set without the necessity ofany particular care being taken, as ywhen the hinge element is providedI` with this leg, it is only necessary that the hinge element be set so that it abuts against the rear corner of the frame with the lower end of the leg resting firmly against the gutter angle. rlhis will bring the upl er edge'ofv fiio and removed as a unit so that it is a very Y easy matter to set the door in place. Y if While I have illustrated certain details of construction and certain arrangements of parts, it will be understood that, the" principle of the invention might be applied to other forms of doors without departing from the spirit of the invention and that the details of construction might be modified in many ways without departing from the spirit of the invention as defined in the appended claims.

I claim:-

1. The combination with a door frame,

2. The combination with a door frame, of a door having supporting gudgeons projecting laterally beyond the side edges of the door, and gudgeon supporting elements having apertures into which the gudgeons extend, said supporting elements being detachably engaged against and projecting from the inner edge face of the door frame confronting the edge of the door.

3. The combination with a door frame, of a door, gudgeons mounted upon the inner face of the door adjacent one end, and gudgeons supporting elements into which the ends of the gudgeons extend for rocking engagement, the gudgeon supporting Y elements being engaged at against the inner surface of opposite corners of the door frame and being detachably engaged with the door frame.

et. The combination with a door frame, of a door fitting the frame and having supporting gudgeons mounted upon the inner face of the door adjacent its rear end, gudgeon supporting elements detachably engaged against the inner face of the door frame and apertured for rocking engagement with the gudgeons, each of the supporting elements being cut away upon its upper face and disposed with the upper face of its rear portion flush with the upper face of the door frame, the door being out away to accommodate the rear portion of the supporting element, that portion of the supporting element below the upper face of the door frame constituting a seat for the door when closed.

5. The combination with a door frame, of a door, the lateral margins of the door at the rear thereof being cut away, gudgeons attached to the inner face of the door and projecting below said cut away portions of the door, gudgeon supporting elements disposed against the inner face of the door frame and abutting against the rear thereof, and detachably engaged with the door frame, each supporting element having an aperture for the corresponding gudgeon and the forward portion of each supporting element being cut away to a level below the level of the upper face of the door frame to receive and form a seat for the door when the door is closed.

6. In a door structure, a rectangular frame having an inner inwardly project-ing flange,
